Abstract: An electromagnetic propulsion system includes a plurality of primary windings and a permanent magnet arranged to move with respect to the plurality of primary windings. A secondary winding of the system is disposed in a non-moving relationship with the permanent magnet. An excitation energy is applied to the plurality of primary windings for creating a magnetic field that includes a base component and low frequency harmonic components. The base component substantially contributes toward motion between the plurality of primary windings and the permanent magnet and the low frequency harmonic components substantially contributes toward generating an electro-motive force in the secondary winding based on displacement between the plurality of primary windings and the permanent magnet.

Abstract: A passenger detector (10) for use in a passenger conveyor system (12) is provided that includes a structured light source (34), a structured light detector (36), and a controller (38). The structured light source (34) is operable to project light (40) into a detection area (32) in a predetermined projected pattern. The structured light detector (36) is operable to generate reflected light signals indicative of light (40) reflected back toward the structured light detector (36) from the detection area (32). The controller (38) is operable to receive the reflected light signals from the structured light detector (36), and operable to process the reflected light signals to make a determination as to whether a passenger is disposed within a detection area (32).

Abstract: A method for monitoring an area includes distributing, by a detector unit, light during a first instance of time in order to characterize the area based on first data associated with the first instance of time; distributing, by the detector unit, light during at least a second instance of time in order to obtain second data; comparing a first portion of the second data to at least one of: a second portion of the second data and the first data; and based on the comparison, signaling an alarm condition by the detector unit when an evolution in the second data is detected in an amount greater than a threshold.

Abstract: Building systems and method of using elevators in buildings are described. The systems include a robot-use elevator system having an elevator car moveable along an elevator shaft of a building, a controller configured to receive requests associated with the elevator system and configured to control operation of the elevator system, and a robot configured in communication with the controller and configured to perform actions within the building, the robot configured to travel within the building in the elevator car. The elevator car is operated using parameters outside limits intended for human use of an elevator car.

Abstract: An illustrative example embodiment of an elevator system includes a destination entry device configured to allow a passenger to indicate an intended destination prior to entering an elevator car and at least one detector configured to detect a proximity between the passenger and at least one other individual that has not indicated an intended destination. A controller is configured to determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual likely is associated with the passenger, will board an elevator car with the passenger, and will travel to the intended destination with the passenger. The controller is configured to assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion.

Abstract: A passenger tracking system includes a multiple of sensors for capturing depth map data of objects. A processing module in communication with the multiple of sensors to receive the depth map data, the processing module uses the depth map data to track an object and calculate passenger data associated with the tracked object to generate a passenger tracking list that tracks each individual passenger in the passenger data from an origin lobby to a destination lobby and through an in-car track between the origin lobby and the destination lobby.
